Overcontribution 401k in 2023, 1099-R reported in 2024, amend 2023 tax return?

Hi,

In 2023, I over-contributed to my Fidelity 401k. Then, in February 2024, I received two payments from Fidelity for the over-contributed amount plus the earnings on that amount. In early 2025, I received two 1099-R (2024) forms from Fidelity—one with distribution code P and the other with distribution code 8. I reported both 1099-R forms on my 2024 tax return, and TurboTax suggested, "looks like you may need to amend your 2023 return." After doing some research, I want to confirm whether I really need to amend my 2023 taxes or not.

Thank you.
